The most important discoveries in astronomy (2022)

Since black holes do not emit anything that we can fix, we simply do not know much about them.

The most confusing of these are supermassive black holes in which millions and billions of solar masses gather. We know that black holes arise from the nuclei of massive dead stars, but how do supermassive black holes grow to such enormous sizes? The new discovery may provide some answers to this question.
– In one tiny galaxy 110 million light-years away, astronomers have discovered one of the smallest supermassive black holes known to date. Just 200,000 solar masses gather in this black hole in the middle of the galaxy Mrk 462.

A “mini” supermassive black hole has been discovered, which is the smallest recorded so far.

As astronomers have discovered, this galaxy already existed 330 million years after the Big Bang.

Its dim light, which is stretched by the expansion of the universe, took 13.5 billion light years to reach Earth.
– The discoverers called the galaxy HD1 and it is a mystery. Scientists do not yet fully know what this galaxy looks like: a star-forming galaxy in which new stars are actively born, or a quasar, or active, huge supermassive black hole at its center.
– If it is a quasar, an increase to the supermassive size of a black hole so shortly after the Big Bang would call into question current patterns of black hole formation and evolution.

The most distant galaxy to date has been discovered, emerging soon after the Big Bang

For the first time in history, evidence of planets or exoplanets orbiting other stars appeared outside the solar system: two rocky planets orbiting a star 2300 light-years away.

Now, 30 years later, the number of exoplanets has increased dramatically. On March 21, 2022, it was confirmed that 5,000 exoplanets had already been discovered. More specifically, the NASA catalog documents 5005 exoplanets, all with their own unique characteristics.

Each of these exoplanets appeared in a peer-reviewed study at the time of the month and was observed by many different methods of analysis and fixation.

This new phenomenon is called micronova and occurs on the surface of white dwarf stars that are actively absorbing matter from a nearby binary companion star. Accumulation of matter in the white dwarf causes localized thermonuclear explosions – micronova.

Earlier this year, astronomers spotted an object that they thought must have been a black hole in our galaxy; This time, this finding is almost confirmed.

The second group of scientists, who conducted a separate, independent analysis of them, came to almost the same conclusion, which further reinforces the idea that we could potentially detect a black hole wandering in the galaxy.

Astronomers at the University of California, Berkeley, Casey Lamy and Jessica Lou came to a slightly different conclusion in a new study. Depending on the mass range of the object, it may be more of a neutron star than a black hole.

The discovery of a black hole wandering in our galaxy has probably been confirmed

A team of astronomers has found an unusual spiral object in the center of Milky Way that resembles a miniature galaxy, but it is not a galaxy within a galaxy. We are talking about a protostar disk, a cloud of gas that feeds and grows the light in it.

The latter is 26,000 light-years away from us and is 32 times more massive than the Sun, and the diameter of the disk itself is 40,000 astronomical units. There are many similar formations in the world, but such a pattern has not been seen by specialists yet. Its distinctiveness lies in the location, stellar mass, and spiral vents that characterize galaxies.

In just 33 light-years from us (yes, on a cosmic scale, this is considered a short distance), an international team of scientists has discovered a multiplanetary system that is one of the closest to Earth.

At the center of the system is a red dwarf star called HD 260655, which orbits 2 super-Earths (larger than Earth but smaller than Uranus and Neptune). Astronomers note that due to such proximity and brightness, the atmospheres of these solid celestial bodies (if any) are very convenient to study in detail.
